INSULATOR AND SUPPORT.

Specification of Letters Patent.

Patented May 28,1912.

Application filed April 24, 1911. Serial No. 623,030.

To all whom it may concern:

Be it known that I, LAWRENCE F. GRES- sn'r'r, a citizen of the United States, residing at Ballinger, in the county of Runnels and State of Texas, have invented a new and useful Insulator and Support, of which the following is a specification.

This invention relates to an improvement in insulators and supports, the primary object of the invention being the provision of a support in the form of a nail which is provided with a driving portion in line with the body of the nail, and with a malleable insulator supporting loop, which is adapted to co-act with and support a sectional insulator.

A further object of the present invention is the provision of a supporting-nail and sectional insulator, which co-acts to clamp the sections of the insulator tightly upon the telephone, telegraph or other electric wire.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can. be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings :Figure 1 is a side ele vation of the insulator. and support in operable relation. Fig. 2 is an end view thereof. Fig. 3 is a side elevation of the support. Fig. 4c is a perspective view of the insulator removed. I

Referring to the drawings, the numeral 1 designates the piercing end of the support, which in this case, and as shown is a nail, but a threaded shank might be employed. Formed at the outer end and in line with the piercing end, is the hammer receiving shoulder 2, while formed integral with the end is the short depending curved lug or arm 4, which with the long curved terminal 5, which is preferably of a malleable metal, forms the insulator support.

It will be noted in Fig. 4 that the sections 7 are provided with transverse grooved portions, the portion 11 of which is shallower than the portions 12 thereof, while the groove 13 is deeper and below the channel 8, for the reception of the reduced portion 14 and the enlarged deep inclined portion 15 of the ridge of the other member 7, the central channel 16 being adapted to enter and aline with the channel 8, to form with the channel 13 a wire receptacle. By this means when the two members 7 are assembled the inclined portions 14 and 15 will be seated within the grooves 11 and 12, the grooves 13 and 16 receiving the wire and forming a bend at this point to lock the wire within the insulator against longitudinal move- -ment, and producing with the arms 1 and 5 a wire clamping insulator.

v The insulator 6, as shown consists of the two sections or members 7, which when abutting form a substantially cylindrical body with the centrally disposed wire receiving groove 8, and the circumferential support engaging groove 9.

In use, the wire is first placed between the sections 7, of the insulator body, and the body is then placed between the arm 4: and terminals 5, the wire man taking a pair of pliers and clamping the terminal 5 closely around the insulator, so that the arm 4 and terminal 5, fit snugly within the circumferential groove 9, of the insulator, and thereby lock the insulator in the clamping end of the nail. In placing the insulator in the clamp, care is taken to have the split portion of the insulator out of line with the open space 10, between the ends of the arm 4: and terminal 5.

What is claimed is An insulator and support therefor, comprising an insulator made in two semi-cylindrical sections, one of said sections being provided with a transverse grooved portion centrally of the flat face thereof, said groove being deeper at one end than the other, the other section being provided with a projection adapted to register with said transverse groove to prevent longitudinal movement of the sections, the two said sections being provided with a concentric wire receptacle when assembled, the transverse projection of one of the sections being provided with a channel whose lower wall is above the respective wall of the concentric channel of the section, to receive the wire and make a bend therein When the sections In testimony that I claim the foregoing are assembled, sald sectlons belng further as my own, I have hereto affixed my slgnaprovlded With a circumferential groove disture in the presence of two Witnesses.

posed in line with the transverse slot thereof, LAWVRENCE F. GRESSETT. 5 and a support adapted to surround and lit Witnesses:

Within said circumferential groove to hold P. M. OLIVER,

the sections in clamped position. W. T. PADGETT.
